- in use; and to this end, it consists in the novel combinations andmeans hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawing, in which like characters designate corresponding parts in allthe views.

Figure 1 is a face view of my windowscreen. Fig. 2 is an enlargedsectional view, partly broken away, on line AA, Fig. 1. Figs. 3 and 4are opposite face views of a corner of my window-screen. Fig. 5 is aplan view of a corner of the frame at an intermediate stage of itsprocess of manufacture.- Fig. 6 is a section on line Fig. 7 is a view,similar to Fig. 5, of a modified construction of a corner of mywindow-screen.

This window-screen preferably comprises two overlapping sectionsadjustable relatively to each other, such sections being duplicates andinterchangeable. It is apparent, however, that each of said sections maybe employed as a nonadjustable screen.

The frame of each section of the windowscreen is composed of preferablytwo strips of sheet-metal, or other suitable material, foldedlongitudinally along their middles for forming channels 1 which receivethe edges of the central part of the section, as the wire-netting 2. Endportions 3, 3 of one of these strips are bent at right angles to themiddle portion 4 thereof, each of these portions 3, 3, 4 forming a sideof the frame of a screen-section, and the two sides of this frame formedby the end portions 3, 3 being slidably engaged with the correspondingsides of the frame of the other screen-section. The parts 5 of saidstrip which are distorted at-the corners of the frame by bending the endportions 3, 3 are preferably compressed upon adjacent parts of saidcorners, the compressed distorted parts on both faces of each of saidcorners preferably lying on opposite sides of lines, as 6, extending fdiagonally through the corner.

{ diagonally through said corners. Such distorted parts may, however, beotherwise i compressed upon the underlying parts of the 1 corners, asillustrated in Fig. 7, in which I have shown the distorted part on oneface i of a corner as of triangular form, and arranged at one side of aline, as 7, passing The other strip of folded sheet-metal of which theerably forms the remaining or fourth side 8 of said section, and theends of this strip are preferably provided with hooks 9 bent around, andslidably engaging, the contigu ous opposite sides of the frame of theother section of the screen, and serving to hold the screen-scctionstogether.

The outer longitudinal margins of the sides of the frames of theoverlapping sections of the window-screen are bent at an angle to theremaining portions of said sides, forming flanges 0n the opposingsurfaces of the screen-sections. As best seen in Fig. 2, the flange 10,on one of the slidably-engaging sides of one of said frames, is locatedoutside of the flange 11 of the corresponding side of the other frame,and the flange 12 on the opposite side of said one of the frames islocated inside of the flange 13 of the corresponding side of said otherframe. Said flanges 10, 11, 12 and 13 form a particularly simple meansfor guiding the sections of the window-screen in their adjustingmovement. The flanges 14; of the sides 8 of the frames of thescreensections tend to prevent the passage of flies and other insectsbetween the opposing surfaces of said sections. Preferably, thewirenetting 2 extends within the channels 1 of the frames of thescreen-sections to near the bottoms of such channels, and consequently,the bending of the outer margins of the sides of these frames forforming marginal flanges on said frames, clamps the netting 2 inposition.

As will be obvious to those skilled in the art, a window-screen of thedescribed construction is economically manufactured and is particularlystrong and durable in use.

What I claim is 1. A frame for a window-screen comprising a strip ofmetal folded longitudinally for forming a channel, and havingangularlyarranged portions for forming a plurality of the sides of theframe, the parts of said strip distorted at a corner of the frame bybending frame of a screen-section is composed, prefthe strip beingcompressed upon adjacent parts of said corner, substantially as and forthe purpose set forth.

2. A frame for a Window-screen comprising a strip of metal foldedlongitudinally for forming a channel, and having its end portionsarranged at right angles to the middle portion thereof, each of saidportions forming a side of the frame, the parts of said strip distortedat corners of the frame by bending the strip being compressed uponadjacent parts of said corners, substantially as and for the purposespecified.

3. A frame com osed of a strip of metal folded longitudina ly to form achannel and bent upon itself to form two or more of the sides of suchframe and having the parts of the metal distorted. at the corners bysaid bending compressed upon the sides at such corners to liesubstantially flat thereon.

4. A Window screen consisting of a frame composed of a strip of metalfolded longitudinally to form a channel and bent upon itself to form twoor more of the sides of such frame and having the parts of the metaldistorted at the corners by said bending compressed upon the sides atsuch corners to lie substantially fiat thereon, and a screen materialsecured in such channel.

5. A frame for a window-screen comprising a strip of metal foldedlongitudinally for forming a channel, and having its end portionsarranged at right angles to the middle portion thereof, each of saidportions forming a side of the frame, the parts of said strip distortedat corners ofthe frame by bending the strip being compressed uponadjacent parts of said corners, and the outer margins of said sidesbeing bent at an angle to the re maining portions thereof, substantiallyas and for the purpose set forth.

6. A frame for a window-screen comprising a strip of metal foldedlongitudinally for forming a channel, and having angularlyarrangedportions for forming a plurality of the sides of the frame, the parts ofsaid strip distorted at a corner of the frame by bending the strip beingcompressed upon adjacent parts of said corner, and the compresseddistorted part on one face of the corner lying on opposite sides of aline extending diagonally through said corner, substantially as and forthe purpose specified.

7. A frame for a window-screen comprising a strip of metal foldedlongitudinally for forming a channel, and having its end portionsarranged at right angles to the middle portion thereof, each of saidportions forming a side of the frame, the parts of said strip distortedat corners of the frame by bending the strip being compressed uponadjacent parts of said corners, and the compressed distorted part oneach face of each of said corners lying on opposite sides of a lineextending diagonally through said corner, and the outer marginsof saidsides being bent at an angle to the remaining portions thereof,substantially as and for the purpose described.

8. A window-screen comprising two overlapping sections adjustablerelatively to each other, the frame of each section being composed ofstrips of metal folded longitudinally along their middles for formingchannels to receive the edges of the wire-netting, such nettingextending into the channels to near the bottoms thereof, one striphaving its end portions arranged at right angles to the middle portionthereof, each of said portions forming a side of the frame, the parts ofsaid strip distorted at corners of the frame by bending the strip beingcompressed upon adjacent parts of said corners, and the other stripforming the fourth side of said frame and being provided with hooks atits ends bent around, and slidably engaging, the contiguous sides of theframe of the other section, and the outer longitudinal margins of thesides of each frame being bent at an angle to the remaining portions ofsaid sides, sub stantially as and for the purpose set forth.

9. A window screen section comprising a piece of screen fabric and aninclosing frame having a plurality of its sides formed of an integralstrip of sheet metal, folded longitudinally and having portions bentangularly with respect to each other to form frame bars, which inclosethe marginal portions of the screen fabric, the surplus metal at thecorners being folded 011 a line disposed at an angle of 45 to anadjacent frame bar, said fold extending to the exterior corner of theframe, and said surplus metal being flattened, to bring it substantiallyinto the plane of the frame and lock the adjacent frame bars in theirrelative angular positions, substantially as described.

10. A window-scrcen, comprising a section of screen material and ametallic frame surrounding the same, a plurality of the sides of saidframe being formed of a single uncut piece of metal foldedlongitudinally upon itself and bent angularly at the corners of theframe, the surplus metal caused by such bending being flattened downinto substantially the same plane as other portions of the frame andserving to reinforce the corners thereof, substantially as described.
